Akali Ability (LoL): Twilight Shroud

Akali drops a smoke bomb, unleashing a spreading cover of smoke lasting 5 / 5.5 / 6 / 6.5 / 7 seconds and granting herself 30 / 35 / 40 / 45 / 50% movement speed decaying over 2 seconds.

Akali increases her energy by 100 while the shroud is active. While inside the smoke, Akali is invisible.
